STARTING STAYER CHAINSAWS WITH WALBRO
COLD MACHINE AND HOT MACHINE
There are two situations of start: with the machine in cold
and hot machine. The machine is considered to be cold
when it does not work over 10 minutes.
HOW TO ELECTRICALLY POWER ON THE MACHINE
(Fig. 15)
Press the power switch on the engine (15) placing it,
according to model, in position position opposite to "STOP"
or "I".
SHUTDOWN OF THE MACHINE
Press the power switch on the engine (15) placing it,
according to model, in position "0" or "STOP" position.
THE BULB PRIMER (Fig. 22)
The bulb of priming (22) is a small bulb of transparent
rubber located outside of the machine. The bulb must be
enough filled (with less than 30% of air) of gasoline. To fill it
press several times until you see gasoline on the
transparent button (22). When the bulb has just enough
petrol, don't continue pressing. If you click more you cannot
start due to flooding the gasoline cylinder. Therefore please
always keep in mind don't abuse of the priming bulb (22).
STARTING CHAINSAW: PROCEDURE OF COLD START
1.Prime the gasoline bulb (22) if necessary. If there's
enough gasoline in the bulb there is no necessity of
prime. In cold conditions you can push one or two times
the bulb before crank. See above general instruction
about the primer bulb.
2.Close full admission of air carburetor, pulling down the
starter (Fig. 21) knob until it enclaves in the "CHOKE"
position.
3.Turn on the power switch on the machine (15).
4.Check that the mechanical brake (Fig. 4) is disabled.
Check that the white transmission plastic piece at the
base is sunken. If is not so, pull the handle towards you,
so the brake is disabled.
5.Hold the machine steady and avoid that there are no
obstacles around the machine. Comply with all security
measures before starting.
6.Crank up machine pulling the start (14) rope vigorously.
Under normal conditions in few attempts you will hear
the sound of the first explosions. As soon as you first
hear the explosions sound please stop.
7.Open full admission of air carburetor pushing the starter
(21) knob until it is in the "RUN" position. This is valid in
90% of the time, but in conditions of extreme cold it
could be necessary to keep the knob in an intermediate
position that is marked with "START" depending on the
model.

STARTING CHAINSAW: PROCEDURE OF HOT START
1.Turn on the power switch on the machine.
2.Check that the mechanical brake is disabled. Check
that the white transmission plastic piece at the base is
sunken. If is not so, pull the handle towards you, so the
brake is disabled.
3.Hold the machine steady and avoid that there are no
obstacles around the machine. Comply with all security
measures before starting.
4.Pull lever start vigorously (14). Under normal conditions
the machine will start at the first attempt.
IF MACHINE DOEN'T START
If standard cold/ hot start method is not working cylinder
could be flooded. Try this
primer bulb in order to ventilate please pull about 8 times of
level with the machine switched OFF (15) and the lever of
"CHOKE" (21) disabled ("RUN" position: completely
introduced). After pull turn the switch ON (15) and pull to
start (14). If it doesn't start, it might be due a large flood. In
this situation before starting you can take out the spark plug
(12) soaked in gasoline and then dry it and wait a while after
assembling and make cold start.
